BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a marker lamp mounted on a large truck or the like.

[0002]

2. Description of the Related Art In a large truck or the like, a marker lamp is attached at a required position so that the height and width of the vehicle can be understood by other vehicles and passersby, and safety measures are taken at night.

Conventionally, for example, a marker lamp as shown in FIG. 5 has been put into practical use as the marker lamp.

This marker lamp 1 has a bottom plate 2 made of iron.
A socket 3 fixed to the bottom plate 2, a light-emitting body 4 attached to the socket 3, a lamp cover 5 surrounding the light-emitting body 4, and a lamp cover 5 for connecting the lamp cover 5 to the bottom plate 2. It is composed of a coupling member 6.

The lead wire L connected to the socket 3 is led out to the outside from a through hole 7 formed in the bottom plate 2, and the through hole 7 is closed by a sealing material 8 through which the lead wire L is passed. It has become so.

The coupling member 6 is a C-shaped metal ring, and the bottom plate 2 and the lamp cover 5 are reduced by reducing the gap between the openings with a screw 9 screwed into the opening. Is designed to be firmly bonded.

[0007]

However, according to the conventional marker lamp 1 described above, since the connecting member 6 is made of a metal ring having a C shape, the joint between the bottom plate 2 and the lamp cover 5 is completely sealed. Therefore, rainwater or the like may infiltrate into the marker lamp 1 and cause poor conduction due to corrosion.

Further, since the bottom plate 2 and the lamp cover 5 are joined by tightening the connecting member 6 made of a C-shaped metal ring with the screw 9, the work of attaching and detaching the lamp cover 5 is very troublesome. However, there is a drawback that it takes a lot of time to replace the luminous body. Moreover,
Since the bottom plate 2 is made of iron, there is a drawback that the corrosion is significant and the durability and appearance of the marker lamp 1 are adversely affected.

Further, the sealing material 8 is made of multi-stage cylindrical synthetic rubber, and since the stepped portion thereof is only in contact with the peripheral surface of the through hole 7, the sealing material 8 when the lead wire L is strongly pulled. There is a problem in that the marker 8 is deformed to form a gap in the through hole 7, and rainwater or the like enters the marker lamp 1 from that portion.

[0010]

In order to achieve the above object, the present invention has a socket on which a light emitting body is mounted fixedly mounted on a disk-shaped bottom plate, and a lead wire connected to the socket is externally attached to the bottom plate. A through hole for leading out to a hole is formed, and a seal material having a concave holding portion for holding the peripheral surface of the through hole is arranged in the through hole, and the bottom plate has a lamp cover surrounding the light emitting body. Is connected with a detachable rubber-like elastic body,
The rubber-like elastic body is annular so that the joint portion between the bottom plate and the lamp cover is pressure-bonded and sealed by the rubber-like elastic body, and the bottom plate is made of resin, and a mounting metal fitting is provided on the bottom plate. The present invention provides a marker lamp structure in which the socket is electrically connected through a conductive plate and can be mounted on a vehicle body by using a mounting bracket for the socket.

[0011]

According to the present invention, the rubber-like elastic body crimps and seals the joint portion between the bottom plate and the lamp cover to firmly bond the joint portion,
Water will be prevented from entering the inside. Further, the sandwiching portion of the sealing material sandwiches and seals the peripheral surface of the through hole to prevent water from entering the inside.

Further, the current supplied to the light emitter is grounded from the socket to the vehicle body through the conductive plate and the mounting bracket.

[0013]

Embodiments of the present invention will be described in detail below with reference to the drawings. FIG. 1 is a perspective view showing a large truck. In FIG. 1, R is a vehicle body, and stays S are provided on the vehicle body R at required locations. The marker lamp 10 according to the present invention is attached to each stay S.

Each of the marker lamps 10 has a vehicle body R.
Power is supplied from a battery (not shown) mounted on the vehicle, so that a light-emitting body described later emits light. At this time, the vehicle height and the vehicle width can be clearly indicated to other vehicles and passersby.

FIG. 2 is a sectional view showing the internal structure of the marker lamp 10. In FIG. 2, 20 is a bottom plate, 50 is a light emitting body, 80 is a lamp cover, and 90 is a rubber-like elastic body.

The bottom plate 20 is a resin disk made of polyethylene, polystyrene or the like, and a through hole 21 having a large diameter portion 22 and a small diameter portion 23 is formed at the center thereof.
Further, annular walls 24 and 25 are provided so as to project along the side surface in the circumferential direction, and an annular groove 26 is formed between them.

On the other hand, a socket 40 is fixedly installed on the upper portion of the through hole 21 of the bottom plate 20 with a conductor plate 30 interposed therebetween.
The lead wire L connected to the bottom surface of 0 is led to the outside through the through hole 21. The through hole 21 is sealed with a sealing material 60, and the light emitting body 50 is attached to the socket 40.

The conducting plate 30 is a conductor made of a rectangular stainless steel plate or the like, and bolts 71, 71 as mounting metal fittings penetrate through both ends thereof. The bolts 71, 71 and a nut 73 screwed into the tips thereof. , 73, the marker lamp 10 can be attached to the stay S or the like.

For this reason, the light emitting body 50 is led through the lead wire L.
The current flowing to the ground is grounded to the stay S via the socket 40, the conductive plate 30, and the bolt 71 as a mounting bracket, which enables the light emitting body 50 to emit light.

Here, the socket 40 has an L-shaped groove 4
1 is formed, and the light emitting body 50 is fixed by locking the pin 51 protruding from the light emitting body 50. Therefore, the light emitting body 50 can be removed by releasing the mutually locked state.

On the other hand, the lamp cover 80 is made of resin or glass having a light-transmitting property and an inverted U-shaped cross section, and an annular flange 81 is formed at the opening edge thereof, and the annular flange 81 is an annular shape of the bottom plate 20. It fits in the groove 26. The joint portion A between the lamp cover 80 and the bottom plate 20 is covered with a rubber-like elastic body 90 for pressure bonding and sealing. It is also possible to form a plurality of irregularities on the inner surface of the lamp cover 80 so as to reflect the irradiation light of the light emitting body 50. At this time, the light emitted from the light emitter 50 is changed to the lamp cover 80.
Since the light is emitted radially from the entire lamp cover 80 without being condensed in the tip direction of the vehicle, the vehicle height and the vehicle width can be confirmed from various angles, and the glare-proof effect in the tip direction is obtained. You can also get

The rubber-like elastic body 90 is made of styrene-butadiene rubber, nitrile-butadiene rubber, chloroprene rubber, butyl rubber, silicone rubber, urethane rubber or the like which exhibits rubber-like elasticity. In particular, the rubber-like elastic body 90 is formed in an annular shape so as to be in close contact with the outer surfaces of the bottom plate 20 and the lamp cover 80 in the vicinity of the joint portion A.

Next, FIG. 3 shows a bottom view of a marker lamp using a rubber-like elastic body having a different form. The rubber-like elastic body 90 shown in FIG. 3 (a) has a larger inner diameter at the bottom surface, and the rubber-like elastic body 90 shown in FIG. 3 (b) has a smaller inner diameter at the bottom surface. In the elastic body 90, the nuts 73, 73 are located apart from each other, and in the rubber-like elastic body 90 in (b), the nuts 73, 73 are located on the bottom surface thereof. The bottom shape of the rubber-like elastic body is not limited, but the rubber-like elastic body 90 shown in FIG. 3B is preferable because the stability when the marker lamp 10 is attached to the stay S is increased. In particular, when the vibration test of the marker lamp 10 is performed with the vibration frequency of 67 Hz and the vibration acceleration of 7 G (G is the gravitational acceleration), the effect of the rubber-like elastic body 90 is good, and the lamp cover 80 has the bottom plate 2.

Next, FIG. 4 shows an enlarged view of the sealing material 60. (A) is a cross-sectional view of the sealing material 60, and (b) shows its mounting state.

The sealing material 60 is made of synthetic rubber or the like,
As shown in FIG. 4A, a sandwiching portion 63 having a concave cross section is formed on the side surface thereof, and a passage 65 for press-fitting the lead wire is formed in the center portion thereof. As is clear from FIG. 4B, the holding portion 63 is located in the small diameter portion 23 of the through hole 21 and holds the peripheral surface of the through hole 21. Therefore, even if the lead wire L is strongly pulled and the sealing material 60 is deformed, no gap is generated in the through hole 21.

[0026]

As is apparent from the above description, according to the present invention, the bottom plate and the lamp cover are joined by the detachable rubber-like elastic body so that the joints are crimped and sealed. Since it is possible to prevent water from entering into the interior of the lamp, and since the lamp cover can be easily attached and detached, the troublesome work of exchanging the luminous body can be eliminated.

Further, since a sealing material having a concave holding portion is arranged in the through hole of the bottom plate through which the lead wire is passed and the holding portion is held on the peripheral surface of the through hole, the lead wire is provided. Even if the sealing material is deformed by pulling strongly, no gap is created in the through hole, and the effect of further improving waterproofness is obtained.

Further, since the bottom plate is made of resin, it is possible to prevent corrosion, and moreover, since the mounting metal fitting provided on the bottom plate and the socket are electrically connected via the conducting plate, it can be grounded.
